Hello,

I have a query like this: `comments(type: All | Upvoted | Downvoted)` and I use `type` as a keyArg.

When user opens the page he fetches all the comments and later he can narrow his search. I wonder if it’s possible to somehow prepopulate store of `type: Upvoted |Downvoted` with the results from `type: All` query. Unfortunately `preloadQuery` doesn’t have `update` function as mutation do so not sure what’s the best way to achiive that.

I tried to use `read` field policy but that gives me `Already recomputing error`  
here is an example of what I tried:

```auto
comments: {
  keyArgs: ['type'],
  merge: mergePaginatedCollections,
  read(existing, { cache, args }) {
    const variables = args as CommentsQueryQueryVariables;
    if (!existing && variables.type !== VoteTypeFilter.All) {
      const d = cache.readQuery({
        query: CommentsQuery,
        variables,
      });

      return {
        ...d,
        comments: {
          ...d?.comments,
          items: d?.comments.items.filter(
            (c) => c.type === variables.type,
          ),
        },
      };
    }

    return existing;
  },
},

```

Thanks in advance for any tips 🙇‍♂️
