Can I retrieve a result from a JQL and use it in the same JQL for a different result?

[Vincenzo Ciaravella]

I need to write a JQL based on the update date which can only be found by another JQL.  I'm trying to set up a query that will work in a Dashboard with minimal intervention.  Trying to render this 2 step JQL into a one step affair

Example

JQL 1: Key = PRJ-1234 (result for update date = 2021-07-29)

JQL 2: Project = PRJ and (updated >= 2021-07-29 and updated < 2021-07-30)

Thanks

Vince

no. JQL just returns a list of issues. it doesnt present any value that can be used to feed another filter.
