Forwarding multiple emails

[cspz]

Hi, has anyone found a way to forward multiple emails to the same address at one time?  Changing email service forces me to forward each individual email which has been kept in a user created subfolder, one at a time, very time-consuming!  If I take the list of emails in that subfolder, is there any way to forward them at one time to my new email address??

Thank you!!
