Bulk edit websession settings

Hi,
I have lots of configured websessions configured and want to adjust some settings for almost all of them.
I marked some in my connections tree and clicked "Batch Edit":


"Edit Entries (session type settings)" is greyed out. What is the right way to edit lots of those session entries at once ?

I'm on RDM 2026.1.2.3 64-bit on Fedora 43 Gnome Wayland.
