Hi 
Do you know if its possible to change a layout ID ?
It can seems useless but would be very usefull for me.
Thanks by advance !
Thank you for your message. It is not possible to specify the ID for a Layout, my apologies for any inconvenience this causes.
Completely up to you but I must admit I’m a little intrigued about your use case. If you’d like to share your reasons for wanting this functionality I’d be interested to know. 
Many Thanks.
