How to change default id:int to name:string in generated url path?

First of all thank you very much for the tool, very useful.
I have some questions waiting for your help.

1. how to change id:int to name:string?

If I run the following commands to generate controller and view, I got a generated path like // GET /pscluster/:pscluster_id/psmeta/:id. Do we have some cli flags to change ":pscluter_id int" to ":pscluster_name string"?

bud new controller pscluster index new create show edit update delete
bud new controller pscluster/psmeta create show edit update delete


// GET /pscluster/:pscluster_id/psmeta/:id

2. why this strange name generated?

when I run bud new controller pscluster/psmeta create show edit update delete, I got a strange struct name, which change psmeta to psmetum

// Psmetum struct
type Psmetum struct {
	ID int `json:"id"`
}

// Create psmetum
// POST /pscluster/:pscluster_id/psmeta
func (c *Controller) Create(ctx context.Context) (psmetum *Psmetum, err error) {
	return &Psmetum{
		ID: 0,
	}, nil
}

3. Underscores become dashes in url

bud new controller ps_cluster index new create show edit update delete
// GET /ps-cluster
