Hello,
Try to use the Header banner feature of our theme from Theme Settings > General > Header banner > enable the option header banner and add the banner content in the form of text and HTML Block.
For the betterment of the Theme you can post your suggestions/requests related to Theme on the following Feature Request thread:
https://xtemos.com/forums/topic/features-requests-2/
So, if the Development Department finds it fits with the Theme environment then surely they will look through it.
Thanks for your understanding.
Best Regards.
