Thanks for your help @v-xida-msft
To explain a little further:
- All my data is contained within one entity which is called Lead Generation Details
- Each of my product's are their own field. Each field has a field type of Boolean and displayed like shown below with my user input form:

- When my user base is selecting an instrument (currently) will select which instrument they want to submit a lead on (see below). They can select as many instruments as they would like to just to add

- The good news is i already use the patch function (due to having 4 pages of input fields within one entity) though the bad part is when one of my users submits say more than 1 instrument within the one submission, it will come through as one record (as shown below)

What would be great to understand is there a way of automatically adding another record is more than 1 instrument is picked? Or do you have any other suggestions on maybe ways to approach this design?
Thanks again @v-xida-msft
