InfoPath user defined controls

[A.M]

Hi,



I have a sophisticated repeating table that I need to have it for different
sections in my form.



When I copy and paste the table, InfoPath pastes the table with controls
bind to existing data field. Can I make InfoPath to paste the controls with
new data field and group items?



Or generally speaking, is there any way that I create user defined controls
(composition of existing InfoPath controls) and use them in different forms?



Thank you,

Alan
