@mebelousov There're many options for how to specify which result to be
stored into resource pool.
e.g.
```
%spark(saveToResourcePool=1,2,4)
```
Or
```
%spark(1.saveToResourcePool=true, 2.saveToResourcePool=true,
4.saveToResourcePool=true)
```
We can discuss more about which is the best approach, the key point here is
to allow user to customize it via paragraph levle properties.---
