Adding a group feature


I really like to have a tidy and organized space in portfolio perfomance. Would be possible to add a grouping feature like in excel?
The idea would be to monitor/ separate different types of investment/ funds I have.
For example: I have funds with multiple Shares or other funds below. I would like to have at the top row the fund I am investing in and below (with grouping feature so that I can close them or hide them) all the rest. Do you think is possible?

You can sort/group by classification in some views.

That is not possible. If I am not mistaken, it is because of a technical limitation of the library. Therefore there is actually no possibility to solve that.
