Correct Way to Insert Merge Tags in Links

Correct Way to Insert Merge Tags in Links

I'm using Zoho Campaigns and Survey.  I need to create a link to the survey in the email and I also am using custom Unsubscribe copy so I need to be able to create a link for that as well. 

I know the tags are $[ZC:SURVEYURL]$ and $[LI:UNSUBSCRIBE]$.  But I need to be able to control the text of the anchor and if I create a link in the editor by highlighting the text I want to use and entering the merge tag as the URL.  It doesn't work, I believe it prepends http:// or https://  resulting in the protocol being entered twice.  I'm also not sure if it even gets changed to the correct URL.  I also tried putting the actual URL in the link, which generates the correct link but when I go to create the survey campaign it tells me I'm missing merge tags.

I was able to work around this by using the code button in the editor and manually setting the href to the merge tags.  But it seems like there has to be a better way.

Thanks
