Custom CMS Templates not Exported
 

I made some changes to CMS templates within a custom style, I the exported the style to import elsewhere - (lets call this "Style 1"). The custom CMS templates did not come across.

So I had a look at the export style options and saw you could pick a product, I picked vBulletin CMS and exported the style (lets call it "Style 1 CMS") - this time the resultant XML file contained only the customised CMS templates.

So I imported "Style 1" and then imported "Style 1 CMS" and merged it with "Style 1" - strange things resulted with variable names no resolving? I then on a whim imported the "Style 1" XML again and merged it with "Style 1" - voila, all custom templates now show as they should. My question is - is it possible to have all this in a single Style XML and what's with the multiple imports?
