Email in each module

Email in each module

We have a contact ,module which then has a link to customer assets which in turn the asset has a multiple link to service visits.
When we link assets to customers we choose by name and it brings over the associate email via the lookup. Great feature. We can use that email to send merge doc or emails.
When we set up a service visit my thoughts was to do the same but it will not let me pick the email from the asset. Is the solution deluge? In the office the online version will let me create an email and then manually paste in the email address. On the apps it's a big no as there is no email field within the service visit module.
