Transfer between funds "without taxes"

Good Morning
I imagine you already know. In Spain we can make money transfers between investment funds without considering the sale of shares. This is an advantage as no tax is paid on a „Transfer“ only if you make a sale and take money out of the funds.

To have a good reflection of the tax reality in Spain, I need to reflect in some way that transfer of money from one fund to another.

In Portfolio performance, it only occurs to me to make a „sale“ and a „buy“ to reflect that transfer between funds.

And this operation indicates a „realized capital gain“ something that is not correct for our taxation.

Is there a way to do the transfers without the program considering it „realized earnings“?

Can the improvement be included in the program?

Thanks a lot!
