Threshold alerts on custom OID's - Clone custom OID as new

Hi.

The custom OID display low and high threshold as infinite, without possibility to edit the threshold values.

Could we get access to those variables, to be able to create event alerting when a custom OID goes below/above the defined thresholds?

Also, could it be possible to create a button to clone a custom OID, that gives the ability to change the actual OID value before store it as a new one? Very handy when adding a lot of very similar OID's.
