Allocation of Signature Fields to Anyone

Hi,

we use AdobeSign e.g. to collect signatures for participant lists (where users confirm their participation in a training). At the moment, I have to add a signature field for each participant - which can be quite time-consuming when we have around 20 participants.

So my question is whether it is possible to add the e.g. 20 signature fields to the document without assigning them to specific signees (e.g. by using recipient 'anyone')? It doesn't matter which participant signs which signature field in the participant list, and it would make the process faster if I didn't have to selecte each recipient name and then drag/drop the signature field. 

Or does anybody have any other ideas on the best way to manage signatures on documents like this?

Thanks,

Erika
