How to add Quarter as Dimensions & Bifurcation of cumulative balance

[300sss300]

HI

I have data similar as below

Month     Amount

Jan          10

Feb          25

Mar          15

Apr          45

May         60

Jun          35

Jul            45

Aug          80

Sep          100

Oct          105

Nov          90

Dec          80

Q1: How I can add Quarter 1 (Jan -Mar) Q2 (Apr-Jun) Q3 and Q4 as Dimensions or in Coding as Fields

Q2: Above balances are cumulative balances, How I can bifurcate these balances as period balances for each month in Coding or in expression as formula to show in chart or table e.g For Feb Balance should be 25-10 = 15 vice versa 

Regards

Balances can be negative also? Mar - Feb -> 15 - 25 = -10?

Table:

LOAD *,

  Amount - Alt(Previous(Amount), 0) as [Period Balance];

LOAD *,

  'Q' & Ceil(Month/3) as Quarter;

LOAD Month(Date#(Month, 'MMM')) as Month,

  Amount;

LOAD * Inline [
