How to create multiple SSF NFESIG entries in the STRUST transaction

Hello all,

We have one PI + NFE installed and everything was ok until the last weekend, when due to business requirements, we had to add a new certificate from a new company in the STRUST SSF NFESIG.

To use with one certificate is very simple, we just imported the PSE in the SSF NFESIG, but how can we add an additional one? Both of them should exist simultanously.

Thanks in advance,

Roberto
