smart offers and offermative
Can you add integration with this https://www.storeapps.org/product/smart-offers/ ?
basic it should already work with wpfusion, but you would need to develop integration to apply tags based on specific bids created etc.
This plugin also has a sister plugin with artificial intelligence attached to it https://www.offermative.com/ it would be interesting to have tags based on the triggers in this system.(This last plugin is still a bit immature)
