helm-org-ql option to remove filename from query results

Would it be feasible to add an option to suppress the filename from query results? I imagine the current behavior is best for most use cases. However, I do almost all of my queries in a single file and so, for me, the filename simply takes up horizontal real estate.

In case it's unclear what I'm asking, take the following example.
file:
```
* a
** b
```
current query:
```
Query (boolean AND): a
helm-org-ql
tmp.org:a\
```
proposed query:
```
Query (boolean AND): a
helm-org-ql
a\
```
