Template can't be use

[C.c]

Can we clarify this? Do you mean that after creating an object and inputting content to the object, you can no longer change its template?

If so, you might be trying to apply template to an existing object, which is currently still a feature request.

Apply Template to an Existing Object

Is your feature request related to a problem? Please describe. I find myself too often making changes to a template. With this change, I would like to apply these template changes to existing objects. I have to do it manually for all my objects. Describe the solution you’d like Would be great to have a feature to apply changes to a template to existing objects. This option could be optional - depends on the end user if he/she wants to apply changes to the template to existing objects.
