How do I inject cookies when using a cookie jar in CURL?

[iAlbagirl13e]

I am using php curl and i am using the cookie jar for a multi-step crawl. I need the dynamically generated cookies from the server.But at one step some cookies are generated using javascript. Since curl doesn't run javascript I need to inject cookies to curl at this point.The only way I can see doing this is manually reading the cookie file, and setting all the cookies plus the ones I want using \[code\]curl_Setopt\[/code\] and \[code\]CURLOPT_COOKIE\[/code\].Is there a way to inject cookies without loosing the ones already there?
