GB, protected items, any way to do it?

Hi, in HB there is a protected items list, to keep safe items that don't have to be sold or mailed.

Is there any way to do it in GB?

Today I've tryed GBgs and the first thing that was mailed was the mining pick.

I would like to keep my pick

Help my miner to keep his work.

Thanks

 

Everything that is in the default backpack is protected from mailing.

 

many thanks
