I've just updated the AWS Provider, now you can use target profiles either setting an env variable AWS_PROFILE when you add the provider, or setting the option (from CLI or from GUI) to the profile you need
Hi! For now there is no exposed option for profile-selecting in the AWS Provider
You can add multiple instances of the AWS provider and specify token/secret for each of them
But I'll open an issue to investigate how to implement the profile-selection, thanks for the feedback :)
