Do AJO Visual Fragments allow queries?

Question

So with our current ESP we have logic queries in our footers that look like the below to direct them to our ESP's unsub page or our internal hosted unsub page:

<#if unsub-i-is-null>${form('myesp_hosted_unsub', {}, 'EMAIL_ADDRESS_=' + EMAIL_ADDRESS_)}<#else>https://www.mysite.com/page?t=lun&eid=eml-esp-unsub:CAMPAIGNID:${campaign.id};LAUNCHID:${launch.id};LAUNCHDATE:${.now?string(%22yyyy-MM-dd%22)}&unsub-id=${unsub-id}</#if>

Our Footers would be in Visual Fragments and we would use Expression Fragments for static links like our homepage and other fixed info, but this I'm not sure I could do with an expression fragment or not.
