give all my products a new option

We have a shop for cards. Now we have a new option that every product must have.
Now I can open each product separately and give this option, but is there also a way at once to provide this option?

Thanks for your response

What kind of option is that ?
Does the option changes the price of the product ?
Can you give more information on it ?

Its an option that gives a extra price to it.
I have already more options, but this is a new one and it would be nice if i can do al the product in one time...
Custumor can order their invitationcards voor their marriage. it is an option for an extra text printed on the card

There is no option to add such option to all the products at once.

We are currently working on such feature for next version of HikaShop which will be out before the end of June.
