Is there an existing issue for this feature request?

I have searched the existing issues

With many toolchanger printers coming to market, multi-material printing is becoming easily accessible.

Currently, it's not possible to control many important settings per filament:

speeds & accelerations: outer wall, solid infill, infill.
(only limiting speed by max_flowrate is highly insufficent!!)
bridging settings (!): [internal] bridging flow ratio, [internal] bridge density, bridging speed
overhang settings: overhang speed [0..100%]
extrusion rate smoothing

(This list is likely not complete)

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

I would suggest, allowing filament profiles to overwrite all settings of the print profile.

EDIT: It may make sense, to allow overriding of printer profile settings as well: i.e. "Maximum Acceleration for Retracting" for soft filaments

Describe alternatives you've considered

Implement overwrites for all above mentioned settings, and related ones I surely have forgotten.

Additional context

A similar issue exists, but is closed "wontfix" AND also much more narrow in scope (only speeds): #4324.

Therefore I chose to open this issue.
