Passing dynamic search variables. Possible?

Is it possible to pass variables from a form to a grid that pre-populates the dynamic search values?

Here is what I am attempting.
I have a form with a lookup link. This link takes you to a grid of possible options, but I want that grid to be filtered by a dynamic search with variables that can later be modified by the end user if the first initial search didn’t find what they wanted.

Afaik you cannot, but it would be a great enhancement.

I’m thinking thath Could be done manipulating DOM with JS I think. I will try later when have time

Dynamic search allows the user to add fields with arguments in a list. Of course you can manipulate everything with javascript, but it would not be an easy method afaik.

Thank you for the quick responses… I look forward to seeing if @Giu can come up with anything. In the meantime I have figured out how to pass search criteria from my form to a grid for Lookup purposes… but can not figure out how to do it with multiple records. Since the variable keeps getting overwritten each time as its a session variable.
See my screens:
Single Lookup works.

Multiple does not since the variable is overwritten with each row.
