Add string values to a lead layout

Add string values to a lead layout

I'm working on a layout for call center agents that needs to have text prompts for the agent so use during the call.  This will use lead data so the module and layout are easy enough however I'm not seeing the field type I need.  I need to insert text labels, that is fields that are only for displaying text that don't take any input and use record data from the existing record.  For example, a text label that says "Hello ${Leads.FirstName Leads.LastName}..."

This seems like a simple enough process but I can't seem to find any field type that works for this.  Any advice is greatly appreciated.
