I'm using a category selector to filter our sewer mains based on specific lift station basin area when it's chosen in the dropdown. I have it set to pan and zoom to the area then flash the area. I'd like to keep the selection of the area visible highlighted after the flash stops. Is there a way to do that?
Just to make it more clear here is what I'm looking to do. I'd like to keep some color highlight, in the case below it would be cyan of the area that is in focus. Sorry for the poor tracing job on the boundary.

I've seen this asked a few times and it never seems to get an answer. I'd think that something along these lines would be doable, but I suppose it may not be.
Thanks in advance.
