Hi.

I have three tables: 

Teachers - in which all our teachers are listed

Meetings - in which they upload their meeting notes with students

Group Reporting - in which they group and report meeting, but I'd like to make in easier on them and have the pop up that loads all the "meetings" only load the ones that have be done by the selected teacher. if possible also exclude the ones that already have been grouped and reported. 

How is this possible? does it mater that we are using the free plan? 
Also. Teachers aren't "user" they are records in the first table, and all this is done using forms. 

Thanks,

Tomer
