Ticker alternatives for CSV import

Hi,
there are few situations when ticker or ISIN in Portfolio Performance is different than in CSV import.

For example ticker TUI1.DE. It is listed under this ticker in Yahoo Finance so I have it like this in PP.
But XTB exports it as TUI.DE. I can’t import it.
Trading 212 uses TUI1. That should be ok (PP will remove .DE)

Is there any way how to add multiple additional matching symbols?

EDIT: maybe it is partially related to this issue (you can merge it)

Hi, TUI AG primarily trades on the Frankfurt Stock Exchange (XETRA) under the ticker symbol TUI1.DE. However some platforms, including XTB by sounds of it, reference this stock using “TUI” DE and behind the scenes are likely to associate this with the pricing data et al for the official “TUI1” DE listing.

Consequently, it seems this issue is actually caused by a number of platforms . I’m at a loss whether this could be potentially addressed by PP….

You are correct, with XTB the users are not trading directly on exchanges. XTB is the market maker.
