Child Table Field Question

I have a table called "Crane Inspections" that is the child table of a table called "Open Crane Deficiencies". I am trying to have a way to put in deficiencies (up to 4 in one form) that are either existing (noted on previous inspections and still an issue) or new. On the crane inspection form, a crane is selected from a multiple choice field, 23 different questions are completed, then deficiencies (existing or new) are annotated at the bottom.

I have a way that this works now, but I am trying to make better. Right now, I have a pipeline that triggers when a new crane deficiency is put in the form (also up to 4 new ones) and creates open deficiency records in that parent Open Crane Deficiencies table. Our maintenance department goes and works on correcting the deficiency, then closes it out which deletes the record from that table. Meanwhile, on the crane inspection form, that previous open deficiency option will no longer be one on the existing crane deficiencies multiple choice field (the table-to-table relationship field).

My more ideal end state is rather than have to manually select up to 4 existing deficiencies every time an inspection is completed, I would like for the up to 4 fields to be automatically populated with the existing deficiencies from the parent table. Then some way for the inspector to confirm those are still deficiencies, or enter new ones in as I have before.

Please let me know if there is any clarification needed. Any help would be greatly appreciated!
