Adding radio buttons in a repeating table on a insert page

I have an insert page with a form containing 5 fields which are populated by the user entering values.
in the same form I have a repeating table which lists all telephone numbers in the table.

I have added a radio button in the table to enable one telephone number to be selected and added to the form on submit

Can I

1. add a filter to this table with any web assist tools
2. prevent the selected radio option from disappearing if when the table is paginated using next and previous by the user

1) Yes, you can use the database search server behavior.
2) Yes. Save the selected value in the session and then use it to re-populate the previously selected value
