Changing Form Title

Hi Experts,

We have an Agreement Entity and have two different forms on it - Agreement and Request forms.
When creating a record using the Request form, "New Agreement" is showing as the form title and we would like to change it to "New Request" instead. We are using Dynamics CRM 2016 and Dynamics 365 environments. I found a post from MehrCRM but this is in unsupported way community.dynamics.com/.../211553.

Is there a supported way to change the form title? Or if there is no supported way, other unsupported way to change the form title? Thanks!
