Separate prime towers for multi material prints

Is your feature request related to a problem?

On multi-material prints, I'm always frustrated when prime towers break due to dissimilar filaments. Often this will ruin the print. For example: Printing in PLA and using PETG for support interfaces. This works on the model, but sometimes the prime tower will break because PETG does not adhere well to PLA.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

By printing separate prime towers per filament type, they are less likely to break mid-print and cause the print to fail.

As well, separate prime towers would help with filament recycling, as the filament would not be mixed.

Describe alternatives you've considered

There are no alternatives currently.

This feature is literally simplify3d's only redeeming quality. If they had any kind of decent fan control for overhangs and the like, I'd keep using it. But right now I just agonize over the fact that prusaslicer/orcaslicer/simplify3d each has something I need/want to make this idex printer work well.

simplify's purge tower, orca's 3 wall print order, and prusa's mat'l/print settings control. Combine the best of each and you'd have the one to rule them all.
