[Решено] html attribute translation rule

Background of the issue:
Hi, I have an html attribute always translated exactly the same but WPML doesn’t recognize it automatically. The html attribute is related to a button used often on our website and it allows to directly create an email with a subject and content. Translation Memory doesn’t seem to work with html attributes.

Symptoms:
WPML doesn’t recognize the html attribute automatically and Translation Memory doesn’t seem to work with html attributes.

Questions:
Can I add somewhere the translations rules to avoid always manually setting the same translations?
