Update A Form Field By Double Clicking A Query Field

I have 3 peices of data that I am working with: Group number, plans and benefit elections. On my form I have fields for the group number and plan and 2 queries. When I enter a group number the first query displays a list of plan descriptions for that group. From there I can enter the plan description into the form's plan field and that runs the second query to give me a list of valid elections for that plan. This all works fine but I want to make the plan selection a little less tedious. What I would like is to be able to double click the query field housing the plan description and have it copied to the form's plan field. I could use the ID instead of the plan description but I work in a production environment and very key stroke counts so I would really like to have a simple double click process.

Is this even possible? If so how would I set that up? I tried using the double click on event macro builder but it does not seem to have this kind of option.

My form contains fields for group number and Plan. The same form houses 2 querys, one that pulls plans based on the group number and the other to pull elections based on the plan field (not the plan query). Would like to double click a plan within the plan query and have that description populated into the form's plan field.
