Is it possible to allocate data free for certain table?

After deleted a large dataset (~50GB) and optimized tables, some tables have data free (~50GB) and parts of tables have only data free (~KB). As my understanding, the data free are reused and not keeping the ibdata growing. The situation is: My commonly used tables are growing really fast, but unfortunately the data free are allocated to not commonly used tables. The disk space of ibdata is keep growing but the data free is not reused. The question is: Can the data free allocated to commonly used tables, so it can reuse the (~50GB) space, since the storage is costly on cloud?
