Set time delay between the creation and sending of reports when subscribed

Hello, I send a lot of dashboards monthly as a subscription by mail. The text of the mail contains a preview with a link and a png as an attachment. Unfortunately, the reports are not completely structured when the mail is sent, so only dotted circles appear in the emails and the preview.
A dashboard takes about 10-30 seconds to set up. I won't be able to optimize this either.
Is there a possibility to delay the sending time of PowerBI (for example "after 30 seconds at the earliest")
Thank you for your help
