Multiple category and sub-category insertion

[seovisions]

Hello,

I have discovered, quite by accident, that adding categories and sub-categories makes use of a delimiter for multiple entries:

PHP Code:

category1/category2/category3 


This is partially useful in that it shows that datafeedr allows for multiple insertion of category taxonomies. However, it loses it's usefulness because of what this particular delimiter actually does:

PHP Code:

Main Category
Main Category / category1
Main Category / category1 / category2
Main Category / category1 / category2 / category3 


Which, essentially, nests each category followed by "/" into a sub-category of the one right before it. or:

PHP Code:

category1
-category2
--category3 


I've tried all the usual delimiter types to see if I could add several sub-categories under a main category in a single insertion. Such as

PHP Code:

/, |, \, :, `, ~, & 


of which only one has any result.

So my tip is the above, and my question is this:

Is there a delimiter in place to allow for multiple entries when adding categories and subcategories?
