I set up a CRM template using HTML import from Campaigns. When it's being sent in CRM, the header image will need a different link each time. However, when I highlight the image and try to add a link, it gives an error that text needs to be added. There seems to be no easy way for my team to swap out the link on the template when they send. Is this an issue because it's HTML, a general bug in Zoho CRM, or something else?

I could change it with HTML but this template needs to be used by lots of people and most won't be comfortable coding.
