Hello All,  
I have a requirement to maintain data in both memory and file based context(if not present in memory copy from file based context; if not present in file copy from memory based context).  
Generally the context mapping in settings.js looks like the following;

```auto
contextStorage: {
	storeInFile: { module: "localfilesystem"},
    	default : { module: "memory" }
    }

```

To store data to file based context I need to provide flow.set(data, "storeInFile"), but in another node red environment the instead of "storeInFile" someone can use "file" or "fileBased" etc.  
Since I have my "default" key mapped to memory, Is there any way I can use file based storage without mentioning the key name("storeInFile", "file" or "fileBased")?

Thanks in advance

If you don’t specify the name it uses the default.

@dceejay Yes, in my case default is memory and I want to keep that way.  
For now what I did is; get context data using RED object and check any "key" has value {module:"localfilesystem"}, I store that value in my node and provide that while setting flow context. So the key name does not matter it can be "storeInFile", "file" or "fileBased".

Yet to find a refined solution😉
