Acknowledging blocked (MBL) alarms
We have some Harmony tags with alarms that are conditionally inhibited by some other tags. This works well to reduce duplicate and nuisance alarms in the alarm list, however when symbol aspects of these tags are used on graphics, they can't be acknowledged while they are inhibited. We are then stuck with flashing symbols that the operator cannot do anything about until the inhibiting condition returns to normal.
Is it possible to allow acknowledgement of MBL alarms?

Your graphic element aspects can be changed to stop the flashing. The tag's control connection INHB property (to know when the tag is inhibited either manually or from another tag) can then be used in the graphic element for determining the color because the flashing is really just a Logical Color like unackBlockedSymbolDark.
