Adding criteria to Revenue Bands

We have CSMs in the US, UK and soon to be Australia. We want to dictate an engagement model by spend, however the revenue bands need to be a different spend amount per region (due to the ACV material amount being different in one region vs. another). The ideal solution would be to be able to add Criteria to the revenue bands. An example would be that our Community segment in the US is $0-50k USD, but $0-25k GBP in the UK. Is this possible? 
You mean having different revenue bands in different regions (which has different currencies) ?
Second this. Same currency but different amounts based on region. For example, $50k in US could be approached with the mid-tear workflow but same $50k in China is expected to be a hi-touch model.
