How can we improve WHMCS?

Hello
Adding prices Recurring in "Products / Services" or in "Configurable Option Groups" requires effort and time, especially while filling in all the boxes "Monthly, Quarterly, Semi-Annually, Annually, Biennially, Triennially".

suggest
Adding the auto-fill feature to all the boxes, when I add the pricing in the first field "Monthly", a calculation is performed in order to fill in all the fields while allowing the admin to modify the quotations if he wants to add a different price tag.

Thanks
