Switch option for change between auto and predefined in pop_up.

Hello, I would like to make a suggestion that I think could be useful. I do not know if it would be easy or difficult to implement, I only suggest it because from my ignorance I do not see it complicated, it is only an idea. I use the option of show canvas only a lot and I don’t change much of the brush but I do change the standard tip to the texture it has. Could the option of adding a button to change the brush tip between auto and predefined be taken into account, for some time in the future, in the pop_up? Currently I see that you can only add size, opacity, spacing and angle. Thanks and best regards.
