In Confluence, the users can include the Create from template macro in order to allow people to create a page with a specific template in a space by tapping it. One of the configurations for this macro is to select a specific space (if blank, the current space will be selected), but, in this option, there is no option to have a user creating a page in their own personal space.

This is a suggestion to have an option to create a page in the user's personal space. For example, instead of the space name, a "self personal space" value in which would allow different users to use the same button in order to create a page in their personal spaces.
