Is there an existing issue for this feature request?

I have searched the existing issues

I am a regular user of the Flashforge Adventurer 5M (AD5X) and a big fan of your software. I would like to propose a unique feature that could significantly set your slicer apart by addressing one of the biggest pain points in multi-material/manual color change printing: filament waste.

The Problem
Currently, the "Prime Tower" is pure waste. While "Flush into object" exists, the user must manually guess the size of the "purge object" to match the total volume of the flushed filament. If the object is too small, a tower is still needed. If it’s too large, it wastes time and space.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

The Proposal: Dynamic Purge-Model Scaling
I propose a feature (let's call it "Smart Purge Object") where the slicer automatically scales a designated secondary model (like a Benchie or a simple calibration cube) based on the calculated purge volume.

How it would work:

User selects a "Purge Template": A simple, non-critical model (e.g., a low-poly figure or a utility part).
Automatic Volume Matching: The slicer calculates the total flush_volume required for the entire print.
Dynamic Scaling: The slicer automatically scales the Purge Template (XYZ or Z-only) so that its total volume equals or slightly exceeds the required flush volume.
Variable Infill/Perimeters: If the volume is high, the slicer increases the infill density of the purge object first, then its scale, to keep the footprint minimal.

Why this is a Win-Win:
• Eco-Friendly: "Zero-waste" printing is a major trend. Turning trash into a "collection of multi-colored Benchies" or "mystery-color toys" is much more satisfying for the community.
• Marketing Edge: This would be a "world-first" feature. No other mainstream slicer currently offers dynamic scaling for purge management.
• User Engagement: Users will love sharing their "Purge Benchies" (unique, accidental color gradients), creating viral content for your platform.

Describe alternatives you've considered

No response

Additional context

I believe this would be a relatively straightforward algorithmic addition compared to the massive value it adds to the user experience.
