How to Rename Multipage In userforms?

Hello Folks VBA Experts out here,

Im new here ,I hope everything is going fine.

I have some doubts

I tried simple method of caption

   Private Sub CommandButton Click()
   With TextBox20
   UserForm1.MultiPage1.Pages(0).Caption = .Text
   End With
   End Sub

After I re-named it , & clicked Save the userform1 its showing the same Old Name after clickling the userform1, is there any Solution that I can Re-Name my userform-multipages? So that it saves the new name of Multipages,and old one gets deleted, please let me know in the comments Section Below , I have attached a Jpg file for the reference , Please Share your idea friends.#Urgent Thanks & Regards

you need somewhere to store your dynamic changes.
why not just use your project sheet name tabs to populate the multipage tabs on initialisation - solves the problem without resorting to saving captions.
leave the multiform page captions blank in the pages properties.
bear in mind that page references are zero based

Private Sub UserForm_Initialize()
Dim x As Integer
For x = 2 To 6
Me.MultiPage1.Pages(x - 2).Caption = Sheets(x).Name
Next x
End Sub
