Default TimeDimensions when Select Dimensions

Problem

I'm wondering if we can given a default timeDimensions when only selecting dimensions in one query. I mean, it look like cube won't offer a timeDimensions automatically if I firstly choose dimensions. However, if I select measures at the beginning, it will automatically give the first timeDimensions which is defined in backend Schema.

Below are two example, we can clearly see timeDimensions differed from each other.

Firstly choose measures

query  {"measures":["AlarmCodeHistory.count"],"dimensions":[],"segments":[],"timeDimensions":[{"dimension":"AlarmCodeHistory.startTime","dateRange":["2022-09-12T00:00:00.000","2022-09-12T23:59:59.999"]}],"filters":[],"order":[{"id":"AlarmCodeHistory.count","desc":false}],"timezone":"Asia/Taipei"}

Firstly choose dimensions

query  {"measures":[],"dimensions":["AlarmCodeHistory.code"],"segments":[],"timeDimensions":[],"filters":[],"order":[{"id":"AlarmCodeHistory.code","desc":false}],"timezone":"Asia/Taipei"}

My concern is if we don't give a timeDimension automatically, the query might take much time.
