key amount

So, the venders at monuments, I have it set to 5 scrap a key atm for testing. In the vender ui, it shows only 3 options.

1 key for 5 scrap,

5 keys 25 crap,

10 keys 50 scrap. 

That would be a lot of transactions to get to 2500 keys for the highest case. 

How Can I get the key amounts higher per purchase at the venders? 

Example 

500 keys 2,500scrap

1000 keys 5000 scrap

Thanks 

Forget that, I got it figured out.  

Glad you figured it out. If you run into any other issues, let me know. Happy gaming!
