Suggestion: Automatically increase extruder clearance height if necessary to complete objects individually #12815

Is your feature request related to a problem? Please describe.
Hi! I was trying to print several items sequentially using the Complete individual objects option and confusingly got a "Some objects are too tall and cannot be printed without extruder collisions" error. Even if I placed the two objects in a row where one could be completed first, then the next one entirely behind it with a gap, the message persisted, and I tried swapping their positions to no avail, though I think technically it would be fine (at least in that specific scenario) as long as the front-most print is done first.

Describe the solution you'd like
It seems that even if that's not possible, just increasing the Extruder clearance height resolves the issue. Instead of outputting the error, it would be nice if the software simply increased the extruder clearance height to the minimum height necessary to perform the print as it was not clear at all that this was possible. I understand this takes (much appreciated!) effort to implement, so even in the interim a more verbose message explaining that this height can be adjusted to potentially resolve the issue would be nice so it's clear what to do next rather than bailing on the print or going web sleuthing for potential solutions.

Describe how it would work
More descriptive error as an interim solution, extrusion height modification for just the specific print if automated.

Describe alternatives you've considered
Alternative is better error messaging.

Thanks!
