Updating your Gains after every change takes ages

[Steam]

Describe the problem:
Hello every small change that I make my gains calculate new it takes ages and makes it impossible to work efficiently I have about 26k transactions and have to change hundreds if not several hundreds of things or add manually how should I do that if every change needs 30minutes to 2 hours to display

Which exchange/wallet is this regarding?
40 Different wallets and exchanges

How did you import data into this wallet?
Via API

What have you tried to fix this so far?

There needs to be a way to turn off the funtion to automatically re-calculate gains, and then once you are done updating all your wallets you can manually trigger it. Let it process everything and then you can go back and review your changes / fix up anything outstanding etc.

It’s not only annoying for users but it probably puts a massive load on their servers at the same time.
