If you have the Han Solo crew card and also have a Target Lock on an enemy can you spend your Target Lock to change eyeballs to a hits AND re-roll any other dice you want too as well? Or is it one or the other only?

Example. 3 attack dice and you get: hit, eyeball, miss.

Thanks

Both Han Solo's ability and the Target Lock action instructs you to spend the Target Lock. So if you spend it to do one you cannot do the other.

If I have a dollar, and a soda costs 1 dollar, and a bag of chips costs 1 dollar, can I spend the dollar on both the chips and the soda?

No, sadly, these things do not work this way. You have to *spend* the target lock to do either of those things.

Unless Garven's along. He'll buy the soda and then hand the buck to his buddy and let him buy the chips.

Leaving one very confused cashier, I'm sure, along with a possible violation of the law of conservation of mass.
