Prusa Slicer 2.9.0-alpha1 Multiple Bed Colour Changes Carried across from plate to plate

[prowlmedia]

Is your feature request related to a problem? Please describe.
When you create a new plate and drag a part to the next plate. All the layer colour changes have to be done again.

Describe the solution you'd like
Colour changes to be carried across.

Describe how it would work
Either the new plate automatically has the plate colour changes that you frag the object from.
or
You can right click "apply changes from bed x"
or
A saved colour change list - this may work across files too.

Additional context
For me the Multiple plates would be fantastic for the same product but with different number per plate. 2, 4, 8, 10, 20 etc depending on capacity / need / build times.

the current solution is a .3mf per quantity... and if I make a change I have to go though the lot one by one to reimport the STL and export them one by one. With the multiple plates... I could just import once and export once ( I know multiple plate exports are coming later)

You need to zip the 3mf file to post it.
