標註複線的scale比例

想請問版上的高手，我想要有自動標註複線比例的功能，目前code(下方)只能單一選取一個複線，我想要能夠選取多個複線，參考之前用的快速標記的code，應該可以用
(setq dpss (ssget "_:L" '((0 . "*MLINE"))))  這行達到，可是其他部分不太清楚要怎麼修改。想請大家幫忙把code更改成能夠選取多個複線嗎?

(defun c:mldim ( / olsnap dic obj xyz mlsty mlsc pt1 pt2 ang mp mp2 ent dic dict tot)

(setq oldsnap (getvar 'osmode))
(setvar 'osmode 0)

(setq dic (dictsearch (namedobjdict) "ACAD_MLINESTYLE"))

(setq obj (vlax-ename->vla-object (car (entsel "\nSelect mline"))))
(setq xyz (vlax-get obj 'Coordinates))
(setq mlsty (vlax-get obj 'StyleName))
(setq mlsc (vlax-get obj 'MLineScale))

(setq pt1 (list (nth 0 xyz)(nth 1 xyz)))
(setq pt2 (list (nth 3 xyz)(nth 4 xyz)))
(setq ang (- (angle pt1 pt2)(/ pi 2.0)))
(setq mp (mapcar '* (mapcar '+ pt1 pt2) '(0.5 0.5)))


(setq dict (dictsearch (setq dic (cdr (assoc -1 dic))) mlsty ))
(setq tot 0.0)
(foreach ent dict
(if (= (car ent) 49)
(setq tot (+ tot (abs (cdr ent))))
)
)
(setq tot (* mlsc tot))

(setq mp2 (polar mp ang tot))

(command "dimaligned" mp mp2 mp)

(princ)
)

(c:mldim)
