Let page name be set by page template variables

I have a page template with two variables MYVAR1 and MYVAR2. In my template I have used the search macro to setup a search for MYVAR2 in another space. Furthermore, I would like the page name to be set to 'X - Y'. The only way I can achieve this with the current functionality is by telling users to cut and paste a text in the page to the page name text field.

Cut and paste the following text to the page name text field: @MYVAR1@ - @MYVAR2|textarea(1,30)@

...

{search:query=@MYVAR1@|spacekey=SOMEOTHERSPACE}

Is there anyway I have have the page name set automatically for example something like this?

@pagename@=@MYVAR1@ - @MYVAR2|textarea(1,30)@
