When sending e-mails or creating calendar events, there should be an ability to link to or attach existing shared documents already uploaded to the respective troop site.
I agree! It would be better than having to dig it up on my PC to attach.
As an extension of this request, if emailing participants in an event, it would be helpful to have a check box for the already uploaded attachments that need to be re-sent. For instance, I have a packing list and permission slip that I had to download onto the computer I was using to re-upload for the email. These were already attached to the event, but couldn’t be attached to the email.
