Store convolution files on Core

When I try to select a convolution file the screen offers locations on my computer but not on the Roon server - I am sure I could do that some months back.

I prefer to have a list of convolution files in a specific Roon Core folder to select from using either iPad or laptop as control points; now I can only select from the specific computer I have stored them. Maybe I am doing something wrong?

Thanks in advance

It seems you can see the folders on the PC where the control point is accessed.
You can mount a folder from your Roon server if you want.
From iPad you can not set convolution filters.
