How to make certain results appear at the beginning of SORT, followed by all other results?

Hello,

I have some data for "drug_level", that I need to sort based on the day column, but I want the first two results to always correspond to the drug_level on the "screening" and "baseline" days, and then all other days sorted in increasing order. Also if there are more than one values for a certain day, I want them to be averaged. Here is an example XL2BB:

Book1
	A	B	C	D	E	F	G
1	Before sort				After sort
2	Day	Drug_Level			Day	Drug_Level
3	2	8620223			screening	6191016
4	6	7951988			baseline	1238085
5	3	8120872			2	8620223
6	9	1209028			3	8120872
7	baseline	5549070			5	932997
8	7	1262228			6	6792422
9	14	1061300			7	1262228
10	screening	1238085			9	2159194
11	30	33736			14	925183.5
12	22	3576752			22	3576752
13	9	3109360			25	71212
14	5	932997			30	33736
15	25	71212
16	14	789067
17	baseline	6832962
18	6	5632856
