yep! Seeing that you can install these separately, you definitely are setting the PYTHONPATH environment variabl so that either version is found; do the same for GRC_BLOCKS_PATH, so that the two block libraries don't interfere, if you haven't already.
Then: GNU Radio 3.9 respects a new environment variable: GR_PREFS_PATH, which defines where GNU Radio (and through that, GRC) look for configuration. And since GRC saves the opened files in that configuration (at least if my memory serves me well), that would solve this issue.
