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**
```javascript
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**
```javascript
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.
