How to track mortgage balance and escrow balance

I’m just getting started with Stessa to manage a few properties that I have owned for several years.
Through the articles on the site, I have been able to log my last 12 months of principal, interest, and escrow splits, and I can use the escrow account to pay my property tax and insurance. So far I have figured that out.

But how can I use the system to track my loan principal balance as well as my escrow account balance?

One property, for example, I bought in March 2011 and have refinanced it once in 2016.

I would like to be able to propertly track the principal balance remaining as well as see how the escrow account gets depleted and replenished.

Can I do that without having to go all the way back to 2011 or 2016 and enter every mortgage statement? Can I just enter in an intermediate point from a recent mortgage statement?
