OK, I figured the way to solve this.
In the Input Menu 34 that comes when we choose to 'Restore of Individdual Backup Files', you can change the value for Recovery interval to the desired value
BR0657I Input menu 34 - please enter/check input values
-------------------------------------------------------------------------------
BRRECOVER options for restore and recovery
1 * Recovery type (type) ............. [restore]
2 - BRRECOVER profile (profile) ...... [initC73.sap]
3 ~ BACKINT/Mount profile (parfile) .. []
4 - Database user/password (user) .... [/]
5 - Recovery interval (interval) ..... [120]
6 - Confirmation mode (confirm) ...... [yes]
7 - Scrolling line count (scroll) .... [20]
8 - Message language (language) ...... [E]
9 - BRRECOVER command line (command) . [-p initC73.sap -t restore -i 120 -s 20 -l E]
This solves the issue.
