Is your feature request related to a problem? Please describe.
With a consequent block of lines to ignore, it's tedious to add a markdown-exec: hide comment to all these lines.
Describe the solution you'd like
Two new markers to mark the start and beginning of entire blocks to ignore:
```python exec="on"
# markdown-exec: hide-start
...
... # these lines won't be shown
...
# markdown-exec: hide-end
print("...")
