QUESTION:
Is it possible to pass grid selector value to drop down selector in target document in Strategy 9.x and 10.x?
ANSWER:
Yes. Choose "Match selectors by source attribute" when selecting edit links.

Passing multiple selections are possible as well.
NOTE: The attributes in grid must used as selector. Only configuring "Edit links" without using the attributes as selectors does not work.
