Allow other tools to be used on the Multibrush Tool.(Similar to the Mirror Tools.)

This is Google Translate.

I tried to make something similar in krita. ↓

I found that other tools cannot be used on the Multibrush Tool, but the Mirror Tools can.

I don’t understand why there is such a restriction.

Some tools can be very efficient when making certain patterns, but they cannot be used on Multibrush Tool.

I don’t know if anyone else has the same idea as me.

Using the Mirror Tools with the Multibrush Tool can give some interesting and complicated results.
What other tools do you think could be used with the Multibrush Tool?

I want the Multibrush Tool can be used with any other tool that traces strokes.
