Masschanges in Services not possible

[infofrs]

I could filter for the same service check like "NTP time" etc. and get a bunch of services. Migrating it in the service group. No problem. But it is not possible to edit Details for these services like name, warn and crit levels. Only a changing in the service template is working. But that if boring if you use the openitc agent or checkmk and you will need 2 different warn/crit levels for example the disk usage template
