Allow to change the priority of editors in "Content Types" settings

Hi,

I've just installed Wild Web Developer plugin on an Eclipse Java Edition 2023-03 bundle.
This bundle already include an XML editor but I wan't to associate every XML files identified under "Text > XML" in "Content Types" settings page to be opened by Wild Web Developer editor (aka Generic Text Editor).

I didn't find any other solution than adding each file name or extension in the "File associations" settings page ! Which is not really simple.

Is it possible to change the default editor directly in the "Content Types" settings page ?
