How can we improve WHMCS?

Please add possibility to set renew offset for each TLD.

For example: .com, .net. org renew offset is 0 (days we must renew domain without penalty).
But .de is 4 days before expire, then we need pay 30 euro penalty
.be also 4 days, then 50 euro
.gy is 40 days
.nz is 50 days
.lv 40 days and 60 euro
.pl is 0 days

There is no "best" setting for each of them. We already have 753 TLD's in our system.
