I think what you mean is that CDM does not let you set the static thresholds. Specifically, you can't sett the threshold to 85%.
We are working toward support for static Time over Threshold (or "ToT" for short) rules in all probes. Time over Threshold is integral to the Baseline and Threshold engine in UIM (or "BLT" for short). The BLT supports static and dynamic ToT rules, but many probes had defined their own static-threshold functionality before the BLT was introduced.
Therefore, the probes that have their own static thresholds will need to be modified to relinquish that functionality over to the BLT, like they already do with respect to dynamic thresholds. The list of probes you provided are those probes that have already been converted. Thus, they are the probes that also support static thresholds.
CDM is on the planned list of probes to convert to using BLT for this new advanced threshold setting. In the online UIM archive of probes you'll notice the probe called threshold_migrator - this probe currently supports an initial list of probes that it can convert from traditional CFG file settings to using central services like BLT. Check the release notes for upcoming releases of this probe for info about new probe support, including (soon) CDM
