LInking to zen language variation from another page

Here is the plan:

Visitor comes to presentation entry page and from that page has three language options that take him to presentation pages in desired language. From that presentation pages I would like to make a link DIRECT to ZenCart shop, but not to the main page, so forcing the visitor to choose his language option again, I'd like to make a link direct to the language option that is equal to languge in presentation.
First of all is that advisable to do and are there any side effects? If this setup is possible, to which file shall I address my link to point directlly to language variation of the shop?

Just add &language=fr to the URL you're using to send them to your Zen Cart page (replacing fr with the appropriate 2-letter language code

Thank you DrByte:cheers:!
