Converting Existing LLC to Series LLC?

[Nami Do]

So I live in Texas and my LLC is established in TX. I want to turn my LLC to a series type LLC where I can create other llcs. I have form from Secretary of State (Certificate of Amendment). It has a section to Add/Alter/Delete Provision, I am thinking adding verbiage to allow for series LLC formation in "Add provision to the certificate of formation section. This is Form 414 - General Information (Certificate of Amendment).

Are there any Realestate Attorney on here?
