We have no plan or adding InfoPath filters in reporting. We know it would make your migration to the cloud a little bit smoother, but it doesn’t fit in ShareGate Desktop’s current narrative.rbressie commented
Just searched on this too. Sooner or later we all will be tasked with assisting users migrate InfoPath forms to an alternative solution. Knowing how many there are and who owns them is the first step in planning that effort. Please add the report feature to a future release.
