Can I add attachements to cells

We are financial services And i am trying to buikd out a CRM with smart sheets.

WE have to attach documents such as ID Wage Slips Bank statements ect to build up a file. Is there any way i can add these files in each cell

cell ID1 = Photoid.pdf

Cell ID2 = Proofresidence.pdf

Cell ID3 = Payslips.pdf

I know i can attach them at the tsrat of the rows but this is no good for my need. Does anybody know a work around for this I am very surprised this can not be done in smart sheets they can attach images so they could attach pdfs in my opinion

Thansk for your help
