sequential dates issue

[Rinku222]

Hello,
Thank you for the great package.
-->Still i have a small requirement which i am not able to achieve using this package.
i am to create multiple range with fours sequental days intoi two groups.
for example we have dates 2,3,4,5 and i want to create two group of 2 -3 and 4-5 deperately but i am unabel to do that, the package individually makes
sequential dates into one single group.
--> Also if you can see the dotted lines at the end when range is selected, i am not sure if i can achieve that using the current functionality of the package.
--> also is there any functionality to style any date seperately.
thanks in advance.
