Yes. Each plugin lets you link multiple accounts of its cloud provider, and you can choose per module which account to use.
How it works
Cloud accounts are added on the plugin's settings page. When you configure a module (File Browser, Gallery, Upload Box, Slider, Media Player), you select which of your linked accounts the module should use. Different modules on the same site can use different accounts.
This works the same way across all plugins.
What to keep in mind
- Cloud providers throttle API calls per account, so spreading load across multiple linked accounts can help with rate limits in high-traffic scenarios. See Does the plugin have usage limits?
- Accounts can be added or removed at any time from the plugin's settings page.
For step-by-step instructions on adding cloud accounts, see the documentation.
