Email Assist - emailing multiple accounts

Hello

Is there a way for our CSMs to use Email Assist to reach out to contacts across multiple accounts, without the need to create multiple CTAs - one per each account? For example - Linda looks after 25 low touch accounts and needs to follow up with the contacts from these accounts - the template is already created in Email Assist but currently she can email only one account at a time, rather than all her contacts. 

Any ideas other than using JO which we don’t want all CSMs to use? Our team just use their Outlook emails, and don’t even use the BCC to TL link as it requires a specific account to log the coms to, rather than logging it to multiple accounts. 

Thanks
