How to add new batches of stocks to portfolio tracker when I already have an earlier tranche listed?

I buy small batches of the same stock, i.e., buy on the dip and always at different price per share.. But if I already have that ticker symbol in my portfolio tracker it won't let me add a separate new line item. In years past one could add extra lines for the same ticker but not any more. Is there a way to do this? Thank you.
