Standard Source When Writing bold, italic and colors

Standard Source When Writing bold, italic and colors

I urgently need a small update to be able to use color and other basic formatting options for the standard writing source.
I expect this from the old version. I have not been able to use it for 3 years and I always need it.
The way I found it was to put the writing source along with the signature this way:

Name Here

Text here

But users never obey this rule to replace only the field. They erase everything and write in the standard font of the zoho system which only gives me only one font option and size and single black color

Please, now I need more than ever.
Allow me to be able to format the default text as I can format the signature.
Get this for the next two weeks, okay? It's very simple
