Boolean Indicator for Key Frame Status with Grease Pencil Geometry Nodes

Hi, I’d like to suggest adding a Boolean attribute in the Grease Pencil Geometry Nodes Layer Domain to indicate whether the current frame is a key frame.

Right now, detecting this requires comparing data between the previous and current frames using simulation nodes, which works but feels unnecessarily complicated for such a basic check.

A built-in Boolean value would make this much more intuitive and help simplify setups that rely on keyframe-dependent logic.

Thanks for considering this!
