Is writing/reading multiple bits inside a byte supported?

We have a usecase where we need to access single bits inside the same byte, e.g. 
```javascript
{
  type: "BOOL",
  start: 0,
  bit: 0,
  value: true
},
{
  type: "BOOL",
  start: 0,
  bit: 2,
  value: false
},
```
Is that even supported because in datatypes, line 36 the formatter allocates a whole byte for the boolean dbVar.
Thanks in advance!
