Is it possible to bind mesh to armature using its current pose? I am looking for solution where i can import premade clothes which might be in

t-pose, A-pose
slightly out of the bone's default state
or use cloth sim to get a good resting pose with wrinkles and cloth not going inside the body

and get them to follow my main rig without using proportional editing.
I need to export the models with the rig as glb with default pose but would like to use the resting pose cloth sim as it looks the most normal.
python suggestions welcome . Maybe something like :

make the resting pose as default pose
bind mesh rig
revert back to original default pose

You can apply the armature modifier, go into pose mode on the armature and set its current pose as the default (idk what menu, use the search system if need be but pretty sure it’s Pose), then re-create the armature modifier.
