@Victor, yes, got a reply, he’s looking into it…
However I’m going to take a different approach and create a function to auto-tag products by category as they get synced, seems a bit more straight forward for the moment.
Example:
cat 1, cat 2, cat3—-> tag A
cat3, cat4, cat5—–> tag B
then in formulas I just apply the weight limit to the tag (term_ID)
there’s quite a few examples out there to apply the function to auto tag, including some plugins that will do it.
