正则表达式用于捕获重复模式

我从具有重复模式的正则表达式捕获中获得以下正则表达式

([0-9]{1,2}h)[ ]*([0-9]{1,2}min):[ ]*(.*(?:\n(?![0-9]{1,2}h).*)*)

它需要以下字符串

1h 30min: Title 
- Description Line 1
1h 30min: Title
- Description Line 1
- Description Line 2
- Description Line 3

并产生这个结果

Match 1:
  "1h 30min: Title 
  - Description Line 1"

      Group 1: "1h"
      Group 2: "30min"
      Group 3: "Title 
               - Description Line 1"

Match 2:
  "1h 30min: Title 
 - Description Line 1
 - Description Line 2
 - Description Line 3"

      Group 1: "1h"
      Group 2: "30min"
      Group 3: "Title 
               - Description Line 1
               - Description Line 2
               - Description Line 3"

现在，我的匹配1h 30min并不总是出现在新行上。所以说我有以下字符串

1h 30min: Title 
- Description Line 1 1h 30min: Title - Description Line 1
- Description Line 2
- Description Line 3

如何修改正则表达式以获得以下匹配结果？

Match 1:
  "1h 30min: Title 
  - Description Line 1"

      Group 1: "1h"
      Group 2: "30min"
      Group 3: "Title 
               - Description Line 1"

Match 2:
  "1h 30min: Title - Description Line 1
 - Description Line 2
 - Description Line 3"

      Group 1: "1h"
      Group 2: "30min"
      Group 3: "Title - Description Line 1
               - Description Line 2
               - Description Line 3"

我虽然删除\n会解决问题，但最终只会在第一个之后匹配所有内容1h 30min
