Clickable Phone Number or Email in Update

We’d like to embed email addresses and phone numbers into updates and have them clickable. For example, we create items when warranty on a product is expiring to ensure the customer receives a personal contact from us. Some of our customers we have multiple contacts and phone numbers for so we can’t easily just put it all in a column. When I try to add tel:5555551212 into the link it gets an http:// added to the front which breaks it. Would you consider changing how these are handled to allow for tel links and possibly email links?
