You can sort of, but you may not want to :-)
>> test: ["Bug Report" 1]
== ["Bug Report" 1]

== "Bug Report"

Alternatively perphaps a change in your data format (adding some metadata)
will help:
>> test: reduce ["Bug Report" [count 1]]
== ["Bug Report" [count 1]]
>> test/:key/count: test/:key/count + 1
== [count 2]
>> test
== ["Bug Report" [count 2]]
