Change 100items at the same time,from "Clear target prior to import" to "Only update imported cells"

[NachoCuevas]

Hi there!

I would like to know how can I change one settings characteristic in myActions. In particular, would be to change from "Clear target prior to import" to "Only update imported cells" in100 items at the same time, rather than doing so 1 by 1.

It would be very usefull.

Thank you in advance Community!

This setting has to be set on each individual action, there are no bulk updates to any settings in this area.
