Catalog + tiny mce

Hi there again, and i forgot to thanks for the previous answer (catalog list for menu).
i'm encountering a new interesting problem !
:-)
when we write an article (text content), in TinyMce, we have the link btn. in the "popup" we can link a TL image or a TL page or any url of our choice.

i'd like to have a catalog product list menu so we can link product to the page needed, like the image or TL page one.

any advise or ideas? i don't want to change in TL plugins or core and i don't manage to create my own module, so 'ill apreciate some great ideas :)

thanks
