Can Form 1041 with a refund be first electronically filed and Form 1310 with documentation for court appointed representative be mailed after Efiling?

I have completed Form 1041 with a refund.  I want to file electronically but Form 1310 is required.  Can I file electronically and follow up later by mail - Form 1310, or should I first mail Form 1310 and then follow up a week or so later by E-Filing form 1041?
