Projects - Link learners per Grade with learner names

When linking learners to a project by grade, can the learner names populate on the right hand side (rather than just the name of the grade) so that we are able to remove learners that shouldn't be linked to the project (such as leavers or those who are excluded from an event). Our only other option at this stage is to filter through all the learners in the school which is not practical.
