It would be much easier and much more flexible to not depend on predefined pairs to input crypto transactions.

For example you have the price of crypto A and you have the price of crypto B so you can easily calculate the exchange between these 2 cryptos with the date and time.

Currently there must be a pair in the app which enormously limits portfolio monitoring, requires a lot of maintenance and there will never be all the pairs available.

As a paying customer this pushes me to use another application which does not use this archaic system and which allows me to enter all my transactions without any problem.
