Split an account

Hello,
First of all, let me thank you for this amazing app.
Congrats to the devs.

My question here is:
Is there an option to create a cash/securities account where for example, I only have 50% of it?

I will try to explain:
I insert all transactions on that account, but after all, I only want to have 50% of that accounting for my portfolio counts and reports.

Thanks in advance

Two choices:

  1. Enter the full entity portfolio and realise you have a 50% share
  2. Enter 50% of the number of securities of the entity
