Unable to remap Left Click in Synapse 4 without assigning Left Click to another button

I am using Razer Synapse 4 with a Razer Basilisk V3 X HyperSpeed mouse.

Issue:
When I try to assign a different function to the main Left Click button, Synapse shows this warning:

"MOUSE - Left Click: To configure this button, assign the LEFT CLICK function first to another button."

I can remap other buttons such as Right Click without any problem. This restriction only applies to the Left Click button.

What I want:
I want to assign a different function directly to the main Left Click button without having to assign the Left Click function to another backup button first.

Could you please confirm whether this is an intentional restriction in Synapse 4, or if there is a setting, workaround, or supported method to disable this limitation?
