Hi all

Have storage: my\_storage  
identifier: my\_identifier

- identifier is empty or doesn not exists

Id like save data to storage

```auto
{
    "some_attr_A":"&{some_info_A}"
}

```

but if there are some data in storage for “my\_identifier”  
for example

```auto
{
    "some_attr_B":"some_info_B"
}

```

id like to only add

```auto
{
    "some_attr_A":"&{some_info_A}"
}

```

not rewrite

result should be

```auto
{
    "some_attr_A":"some_info_A",    
    "some_attr_B":"some_info_B"
}

```

for example add data from another transformer
