You have a great thing going there, though I'm wondering why don't you move to Google Sheets, since Google Sheets is superior in so many ways.

For instance, my portfolio file on google sheets is able to save my end-of-day portfolio value, without having to open the file at all. Google scripts can be automated to be triggered on a time basis, without requiring one to open the file on a daily basis and pressing macro buttons. So I get a summary of how my portfolio of stocks on Bursa, SGX and HKEX have evolved over the last 3+ years as per the chart below. All without pressing buttons and running macros. I only have to key into my sheet my trades and dividends received, with google sheets taking care of everything else.
