Create a pdf with some fillable sheets made by an external person

Hello, how are you? I hope you are ok. I would like to make an fillable pdf so that the person can write something in my pdf. My question is: This is going to be done by an external person(not for myself), logically through your program but I will not give him all the sheets, only the only sheets that I want to make them editable (so that he can´t copy the whole pdf, you know copyright things). My question is: if he gives me those fillable sheets, is there a way for me to add the rest of the pdf sheets to those edited sheets to create a new pdf but the fillable sheets are still fillable? Thank you very much! Basically, I want to create a new pdf with adobe, with my original sheets (that I have not given to him) and with the fillable sheets that he has made.
