Hello,
Sorry I'm Jerome and not Nicolas.
If you cannot perform the modification yourself, you can see to contact some of HikaShop partners or use the "commercial jobs" section of the forum.
I can add your request in the TODO list but without any schedule of its implementation ; specially because it's not something which can be done with one single modified line, it requires more than that and it requires more than a few minutes.
Regards,
Jerome - Obsidev.com

Also helping the HikaShop support team when having some time or couldn't sleep.
By the way, do not send me private message, use the "contact us" form instead.
