Asset Metadata access

Hi, I'm in need of assistance once again.

I'm trying to replace assets (bitmaps) by searching for keywords in file names and replacing them (e.g. texture_low.jpg to texture_high.jpg).

This part works fine, but my edits have no effect if I'm working on a currently open scene (browing for max file to be edited works fine).

Is there a way to make it work on an open scene?
