Print speed for first layer of interface material?

Is there a way to set the print speed of the first layer of interface material? For example, I use silk PLA as interface material. In some cases, I use PETG for support material. The problem is that when the first layer of silk PLA goes over the loosely spaced PETG support, it runs as full speed. Over support something like this:

Of course it doesn't bridge too well at full speed. The workaround is to set the interface speed to 50% or so, but then for subsequent layers it's just slower for no reason.

I can't make sense of the image.Do you have a sample file? I'd like to take a look at it in PrusaSlicer.

Simple answer is no.  There is no setting to configure a different speed for the first layer of support interface.

@joncl the forums are extremely screwed up these days, I suspect on purpose in order to confuse good information for bad, can you provide a working file and better explanation of what exactly your looking for from slicer. It's normal  these days to see persons asking for things using the incorrect terminology for the thing they want, for example, asking for  (information about "Parts"  when they mean "Objects") this can be cause for the wrong information to be provided. If your willing to provide a file exported from prusaslicer the way you have been working it, people may be able to give you better information. Otherwise not.
