Adding Open Short Positions

Is it already possible to add a “short position”? Starting with a sell position and closing it with a buy position? I am considering using Sharesight or alternatives. I am usually a long investor, but some past trades are short trades. I need to include those in the P/L.

My work around so far is
Short selling is basically selling first, and buying later.

I just swap the dates, keep the record, and when the short closes, you add the dates manually.

Definintely a work around.
Sharesight definintely needs to add this, its like half the world doesn’t exist.

Still waiting on this.
Sharesight: Unlike some of the other features, you are 100% losing customers over this.
