Summary

When a user adds an email address on a Text Field (single line), the email address is added with a "mailto:". It would be nice to have an option to not add the "mailto:" string since this might make it harder to copy the field value. 

Steps to Reproduce

1. Create a custom field with the Text Field (Single Line) type
2. Enter the email address on the field

Expected Results

Add an option to remove the "mailto:" string from an email address string in a custom field.

Actual Results

Currently, if you add the email address in the custom field, it will add the "mailto:" string.

Workaround

No workaround
