support for Bedrock Cross region inference profile from model selection drop down

[ramammah]

Please allow for Bedrock Cross region inference profiles, in US, EU and APAC. This will allow for twice the network throughput.
If an enterprise needs to use this plugin with their own Gateway layer, is there options to add something like LiteLLM, where We can track how developers are using with some kind of custom header that this tool can inject and we can get those cost reports from liteLLM ?
