Link Spreadsheet to Business Schedule

Is there some way that I can link a spreadsheet that has the source information for the business/farm schedule to that schedule so that I can quickly pull it up to see what detail regarding what comprises the totals that were entered. It would be nice to be able to “tie” the spreadsheet containing the detailed information for the business schedules so they can be quickly assessed.
I thought I had seen something about how to do this since you cannot import an excel file into Doccycle (which would be very very useful) but cannot seem to find it anywhere if there was something about how to do this.

You can link an Excel file (or any number of other types of files) to most cells in TaxCycle. Just drag and drop it onto the cell you want to link it to.

Thank you so much. I thought it was on the link portion of the program.
Very much appreciate your help.
