[Question] Different argument types based on previous argument

I've recently started looking into this command framework for Spigot plugins and it's very nice. I've run into a bit of a design issue and am unsure if there's any way to get it to work using this framework.

Currently, I have the following commands:
`/rs give block `
`/rs give spawner `
`/rs give entity `

This works as I would expect it to using the following code:

```java
@CommandAlias("rs|rosestacker|stacker")
@Description("The base RoseStacker command")
public class RoseCommand extends BaseCommand {

@Subcommand("give")
@Description("Gives stacked items")
@CommandPermission("rosestacker.give")
public class GiveCommand extends BaseCommand {

@Subcommand("block")
@CommandCompletion("* @stackableBlockMaterial @amount")
public void onBlock(OnlinePlayer target, Material material, int amount) {
// TODO
}

@Subcommand("spawner")
@CommandCompletion("* @spawnableEntityType @amount")
public void onSpawner(OnlinePlayer target, EntityType entityType, int amount) {
// TODO
}

@Subcommand("entity")
@CommandCompletion("* @spawnableEntityType @amount")
public void onEntity(OnlinePlayer target, EntityType entityType, int amount) {
// TODO
}

}

}
```

However, I would like to move the player argument to before the next subcommand name like so:
`/rs give block `
`/rs give spawner `
`/rs give entity `

I haven't been able to think of a way to do this using this command framework. Is such a thing even possible? If it is, could somebody provide some insight on how I could go about doing it? Thanks in advance!
