Helical mask for 2D classification

Helical Processing
1

Hi, is it possible to apply a helical mask during 2D classification in CryoSPARC?
It would be helpful when the filaments are highly bundled.
I attached the illustration of helical mask implemented in Relion.
One needs to specify the outer diameter (and inner diameter) of the filaments.
The helical mask will be multiplied by the existing circular mask.
