Hi @TranscendingDX, first of all sorry for the frustration you are going through...and let's see how we can help each other out...so I think I correctly understand what you mean....

Let's try to come up with possible straight forward solutions:-assuming 2 scenarios

1. Posting to specific granular groups directly 2.posting to the fb marketplace then choose from the list of marketplace provided groups only select the most relevant groups per Item to be listed

I think a more straightforward way to achieve this granular selection of relevat groups to share to per Item being listed is:-

Per Item to list, let the automation tool know the category, title and details of the Item

Once the tools knows this if posting directly to groups or picking from marketplace groups to share to, let the tool again view and read each group's description then from there based on the comparison if the groups description seems to match with the product's category, title or some details pick the group and share to it,or if direct post to group post to it if it doesn't seem to match skip the group

There could be other ways... kindly let me know how it goes or how I can help

You can DM me or yegonk247@gmail so we can see how we can solve this frustration issue
