Mailto - more than 1 email address in the CC

Here is the top part of the formula I'm using to automate the sending of an email to specific users:

var text URLONE = URLRoot() & "db/" & Dbid() & "?act=API_EditRecord&rid=" & ToText([Record ID#]) & "&_fid_662=" & ToText(Today());

var text URLTWO= 

"MailTo:"& URLEncode([Contact Main Email])
&"&cc="& URLEncode([Contact Secondary Email])
&"&bcc=email@email.com"
// the above text invokes the mail client, and creates the TO line
&"?subject=" &  "Store " & [Store No] &  " POS Checkout Site Readiness Survey"

I need to BCC two email addresses. These addresses will always be the same for every email. Is there a way to have two emails in that line? I've tried putting a ; after the first email and then putting the second, but this doesn't seem to work.

While we are at it, is there a way to change the From to a specific email address? I have been having to change that manually to make it come from our project mailbox, rather than my personal email.

Thank you,

Kim
